I did a lot of online research and with Polk's name having been around now for more than 50 years, I decide to try the Monitor 40 Series II speakers. The power of these speakers. Highs were sibilant, especially on cymbals. The sounds is clear and the speakers are able to portray an amazing sound with bass and clarity. Bass was. They have. This is a GREAT chorus pedal for bass!. It is easy to setup and connect. If you are needing heavy bass built into the speaker look at more expensive options.

CX Highlights Fits virtually any smartphone brands in the market* Great bass-driven stereo sound Easy management of tracks and calls*. Klip Xtreme Obsession Stereo Headphones with Microphone- Over-ear with In-Line Command capsule- Large 40mm Speaker Drivers for Great Sound & Bass- mm. Right out of the box these speakers have a harsh tone with male vocals to the point of being strident. These speakers will absolutely shine for you if you let them do their job. I bought this chorus pedal to use with a bass i don't play/own a guitar, so my opinion applies only to bass guitar.
